Description

Technical Field

[0001] This utility model relates to the field of line protection technology, specifically a conductor tension threshold early warning anti-drop-out reinforcement device based on the Beidou positioning system. Background Technology

[0002] Long-term vibration and wear at the contact points between the conductor and the fittings, or between the conductor and the crimped tension clamp, can cause the outer strands of the conductor at the junction to break. If this is not detected in time or if the conductor suddenly falls off due to other problems, it can lead to line failure.

[0003] In existing technologies, an anti-drop device is typically installed between the ground wire clamp and the DB adjustment plate. This device mainly includes a spare wire or an extension rod. If the ground wire drops, the spare wire or extension rod will pull the ground wire to prevent it from falling completely. However, since the spare wire or extension rod is not under tension in the initial state, both ends of the spare wire or extension rod are in a relatively slack state. This can lead to contact between the spare wire or extension rod and the ground wire, causing a malfunction. Utility Model Content

[0004] To address the problem of potential contact between the spare wire or extension rod and the ground wire in existing technologies, which could lead to malfunctions, this invention provides a ground wire tension threshold early warning anti-drop reinforcement device based on the BeiDou positioning system, which can prevent the spare wire or extension rod from contacting the ground wire.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system, including an extension rod and a Beidou positioning module. One end of the extension rod is connected to a DB adjustment plate located at one end of the conductor through a force sensor, and the other end of the extension rod is connected to the middle of the conductor through a wire clamp. The force sensor and the Beidou positioning module are electrically connected to a controller.

[0006] An isolation assembly is provided between the extension rod and the ground wire. The isolation assembly includes a connecting ring, on which two coaxial fixing bolts with opposite thread directions are threaded. A mounting block is rotatably connected to one end of the fixing bolts located outside the connecting ring. The mounting block has a through hole for accommodating the extension rod or the ground wire.

[0007] As a utility model, a conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system is further optimized: the through hole is connected to a receiving groove for accommodating the head of the fixing bolt.

[0008] As a utility model, a conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system is further optimized: the part of the fixing bolt extending out of the mounting block is fixedly fitted with a limiting ring that contacts the surface of the mounting block.

[0009] As a further optimization of the conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system, the extension rod is fixedly provided with mounting rings at both ends. One mounting ring is connected to the force sensor through a bowl-head hanging ring, and the other mounting ring is connected to a first lifting eye bolt through a first connecting piece. The rod of the first lifting eye bolt passes through the through hole and is connected to the wire clamp through an adjustment component.

[0010] As a further optimization of the conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system, the first connector is set as U-shaped, and the two sides of the first connector are connected to the mounting ring by connecting bolts. The bottom of the first connector is located inside the head of the first lifting eye bolt.

[0011] As a further optimization of the conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system, the adjustment component includes two adjustment rods, a transition shaft is provided between the two adjustment rods, the transition shaft is connected to an anti-detachment disc through a connecting shaft, the adjustment rods are provided with a slide for the connecting shaft to pass through, and the rod body of the first lifting eye bolt passes through the transition shaft and is fixed by a fixing nut.

[0012] As a further optimization of the utility model of a conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system: the end of the conductor extending out of the clamp is connected to the DB adjustment plate through a connecting sleeve.

[0013] As a utility model, a pre-warning anti-drop reinforcement device for conductor tension threshold based on Beidou positioning system is further optimized: a second lifting eye bolt is screwed to one end of the connecting sleeve away from the conductor, and the head of the second lifting eye bolt is connected to the DB adjustment plate through a second connector.

[0014] As a further optimization of the conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system, the DB adjustment plate and the force sensor are connected by a Z-shaped mounting plate. The Z-shaped mounting plate includes two parallel mounting plates, which are connected by a connecting plate. A first mounting bolt is slidably arranged between the two mounting plates. The force sensor is connected to the first mounting bolt through the connecting plate. The two mounting plates are connected by a second mounting bolt, which passes through the DB adjustment plate.

[0015] As a further optimization of the conductor tension threshold early warning anti-drop reinforcement device based on the Beidou positioning system, the mounting plate has a channel on the surface near the connecting plate for the connecting plate to pass through, and the first mounting bolt passes through the connecting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1) This utility model incorporates an extension rod and a Beidou positioning module. One end of the extension rod is connected to a DB adjustment plate located at one end of the ground wire via a force sensor, and the other end of the extension rod is connected to the middle of the ground wire via a wire clamp. The force sensor and the Beidou positioning module are electrically connected to a controller. To prevent damage caused by a broken ground wire, the extension rod is connected to the middle of the ground wire. When the ground wire is damaged and broken, the tension value sensed by the force sensor changes. At this time, the Beidou positioning module can assist staff in determining the specific location of the broken wire for quick repair.

[0018] 2) This utility model provides an isolation component, which includes a connecting ring. Two coaxial fixing bolts with opposite thread directions are threaded through the connecting ring. An installation block is rotatably connected to one end of the fixing bolts located on the outside of the connecting ring. The installation block has a through hole for accommodating the extension rod or the ground wire. This avoids the occurrence of malfunctions due to contact between the extension rod and the ground wire. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art. For example, what is the ground wire 1, the specific structure of the wire clamp 2, the specific structure of the bowl head hanging ring 13, the specific structure of the first lifting eye bolt 5 and the second lifting eye bolt 12, the model and working principle of the force sensor 14, the structure of the DB adjustment plate 16, what is the insulator string 17, and how the Beidou positioning module and the force sensor 14 are connected to the controller, etc.

[0026] Example 1

[0027] A conductor tension threshold early warning anti-drop reinforcement device based on the BeiDou positioning system, such as... Figures 1 to 5As shown, the device includes an extension rod 9 and a Beidou positioning module. One end of the extension rod 9 is connected to a DB adjustment plate 16 located at one end of the ground wire 1 via a force sensor 14. The other end of the extension rod 9 is connected to the middle of the ground wire 1 via a wire clamp 2. The force sensor 14 and the Beidou positioning module are electrically connected to a controller. The DB adjustment plate 16 is connected to an insulator string 17. To avoid damage caused by the ground wire 1 falling off, the extension rod 9 of this invention is connected to the middle of the ground wire 1. When the ground wire 1 is damaged and falls off, the tension value sensed by the force sensor 14 changes. At this time, the Beidou positioning module can assist the staff in determining the specific location of the fallen wire for quick repair. To ensure that the force sensor 14 can better detect the tension when the wire is disconnected, the connection between the extension rod 9 and the clamp 2 of the ground wire 1 is initially slightly loose. At this time, the force sensor 14 experiences almost no or no tension. However, this can easily cause the extension rod 9 to come into contact with the ground wire 1, thus affecting the working effect of the ground wire 1. An isolation component 7 is provided between the extension rod 9 and the ground wire 1. The isolation component 7 includes a connecting ring 706, on which two coaxial fixing bolts 704 with opposite thread directions are threaded. When it is necessary to adjust the distance between the extension rod 9 and the ground wire 1, the connecting ring 706 is rotated so that the two fixing bolts 704 move closer or further away at the same time. To prevent the extension rod 9 and ground wire 1 from rotating together during adjustment between the connecting ring 706 and the fixing bolt 704, a mounting block 701 is rotatably connected to the end of the fixing bolt 704 located outside the connecting ring 706. The mounting block 701 has a through hole 702 for accommodating either the extension rod 9 or the ground wire 1. Thus, even if the fixing bolt 704 rotates to a certain extent, the mounting block 701 will not rotate because it is rotatably connected to it, thereby ensuring that the extension rod 9 and ground wire 1 do not rotate. The extension rod 9 can also be replaced with a spare wire.

[0028] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0029] Example 2

[0030] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: When the fixing bolt 704 passes through the mounting block 701, the head of the fixing bolt 704 occupies a certain space in the through hole 702, which may interfere with the passage of the extension rod 9 or the ground wire 1. Therefore, the through hole 702 is connected to a receiving groove 703 for accommodating the head of the fixing bolt 704. To prevent instability in the vertical position of the mounting block 701 when the connecting ring 706 rotates and causes the two fixing bolts 704 to move closer or further apart, a limiting ring 705 is fixedly fitted onto the portion of the fixing bolt 704 extending out of the mounting block 701, contacting the surface of the mounting block 701. This ensures that the mounting block 701 is stably positioned between the head of the fixing bolt 704 and the limiting ring 705. During processing, a through groove can be made on the mounting block 701 to allow the fixing bolt 704 to pass through. The inner diameter of the through groove is smaller than the diameter of the extension rod 9 or the diameter of the ground wire 1 to ensure that the extension rod 9 and the ground wire 1 will not fall out of the through groove when passing through the through hole 702. The fixing bolt 704 enters the through hole 702 of the mounting block 701 from the through groove. Then, the head of the fixing bolt 704 is located in the receiving groove 703. The rod of the fixing bolt 704 passes through the mounting block 701. After the rod passes through, the limiting ring 705 is sleeved on the rod to weld the two together.

[0031] Example 3

[0032] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that, in order to ensure the connection between the extension rod 9 and the force sensor 14 and the mounting block 701, mounting rings 10 are fixedly provided at both ends of the extension rod 9. One mounting ring 10 is connected to the force sensor 14 through the cup head hanging ring 13, and the other mounting ring 10 is connected to the first eye bolt 5 through the first connector 8. The rod of the first eye bolt 5 passes through the through hole 702 and is connected to the wire clamp 2 through the adjustment component.

[0033] Example 4

[0034] This embodiment is an improvement on embodiment 3. Its main structure is the same as that of embodiment 3. The improvement is that, since the first connecting piece 8 is to connect the mounting ring 10 and the first lifting eye bolt 5 respectively, the first connecting piece 8 is set as U-shaped for easy connection. The two sides of the first connecting piece 8 are connected to the mounting ring 10 by connecting bolts. In this way, the first connecting piece 8 and the mounting ring 10 can move to a certain extent. The bottom of the first connecting piece 8 is located inside the head of the first lifting eye bolt 5.

[0035] Example 5

[0036] This embodiment is an improvement on embodiment 3. Its main structure is the same as embodiment 3, but the improvement lies in the following: the adjusting assembly includes two adjusting rods 3, with a transition shaft 18 between them. The transition shaft 18 is connected to an anti-detachment disc 6 via a connecting shaft. The adjusting rods 3 have slides 4 for the connecting shaft to pass through. The first lifting eye bolt 5 passes through the transition shaft 18 and is fixed by a fixing nut. The adjusting rods 3 and the wire clamp 2 are also rotatably connected, allowing the adjusting rods 3 to rotate as needed and change the distance between the extension rod 9 and the ground wire 1, working in conjunction with the isolation assembly 7 for adjustment.

[0037] Example 6

[0038] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in that: one end of the ground wire 1 extending from the clamp 2 is connected to the DB adjustment plate 16 via a connecting sleeve 11. A second eye bolt 12 is screwed onto the end of the connecting sleeve 11 away from the ground wire 1, and the head of the second eye bolt 12 is connected to the DB adjustment plate 16 via a second connector. The second connector can also be U-shaped, with both sides connected to the adjustment plate via bolts. The connecting sleeve 11 serves as a drain tube, which can dissipate a portion of the tension on the ground wire 1. The drain tube is conventional prior art in this field and will not be described in detail here.

[0039] Example 7

[0040] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: To facilitate the connection between the DB adjustment plate 16 and the force sensor 14, and to allow for a certain degree of movement between them, the DB adjustment plate 16 and the force sensor 14 are connected by a Z-shaped mounting plate 15. The Z-shaped mounting plate 15 includes two parallel mounting plates 1501 connected by a connecting plate 1505. A first mounting bolt 1503 is slidably disposed between the two mounting plates 1501. The force sensor 14 is connected to the first mounting bolt 1503 via a connecting plate 19. The two mounting plates 1501 are connected by a second mounting bolt 1504, which passes through the DB adjustment plate 16. A channel 1502 is provided on the surface of the mounting plate 1501 near the connecting plate 1505 for the connecting plate 19 to pass through, and the first mounting bolt 1503 passes through the connecting plate 19.
